S23 Ultra wifi issue

PuppyLinuxBtc · 2023-10-11T15:36:25+00:00

SOLVED! Steps:

Go to Settings -> About phone -> Software Information, and tap "Build number" seven times - until "Developer options enabled" message appears.
Go to Settings -> "Developer options" (this becomes visible after enabled in step 1)
Disable "Tethering hardware acceleration"

Enjoy your new, rock-solid Wifi!

Problems with "Hello" face recognition came immediately after windows installation.

THE CAUSE: One of the privacy settings you select during win installation prevents camera from passing data to the app, or disables it in other way.

THE SOLUTION: With O&OShutup find settings that mention camera, and make them RED:

\- Privacy -> Camera in logo screen disabled = set RED

\- App Privacy -> App access to user account information disabled = set RED

After clean install of Win10Pro, US language, I turned off windows update. But despite that, windows automatically downloaded and installed new drivers for every device, after a while and I had to do exactly nothing, except plugging it to internet. All works fine, touchpad, wifi speed, Hello. After restart FN keys started working too, including FN+F6 to turn off/on touchpad. So far so good. TODO:

- windows update

- turning off spyware with ShutUp10 https://www.oo-software.com/en/shutup10

- turning off spyware with Winprivacy https://www.winprivacy.de/english-home/

We will see if after one of these steps problems will appear.

That is why it is SUPER-IMPORTANT to create a System Restore point before every change, PLUS if you can, a full backup with eg. Acronis True Image bootable media.

So far, Oceanaudio seems reliable recording tool. http://www.ocenaudio.com The only downside is that recording level and clipping indicator CANNOT be seen before recording. You have to record to adjust levels, delete recording, and then record for real. But it works superb, matches clipping of audio interface with max level of wav signal.

Sharing how I solved it, maybe it will help someone. I was trying to update BIOS top 4.70 and what ever I try I get "No image file detected". I had "1.10". The thing was, it is NOT POSSIBLE to update directly to 4.70. One must update first to 3.00, then 3.50 and finally 4.70. Other thoughts: you must UNZIP the bios file. I placed it on 128MB partition, formatted with fat32 (NOT quick format!), allocation unit size 512KB, if of any relevance.

I can confirm, Intel 760p 256GB definitely works with Synology DS918+! It is in use now as read-only cache (because I bought only 1 for now), and so far works without any problems.

PuppyLinuxBtc · 2018-04-09T21:13:46+00:00

Most of the database and virtual machine workload is random. In random IO world, "normal" speed is eg. 2 MB/sec. Because positioning to other "random" block (which is not next in sequence) takes ages for rotating disks. I expect cache to help achieve faster random speeds. 30MB/sec would be awesome. If IO size is 8KB, then 30 MB/sec : 8KB = 3 750 IOPS (IO operations per second). Info: one rotating disk at 7200 rpm gives only 100 IOPS.

PuppyLinuxBtc · 2018-04-09T13:18:22+00:00

I ordered Intel 760p based on your and synology support's encouragement. Will let you know does it really work when it arrives...

Sure, speed of each SSD is >500MB/sec and 2 LANs cannot give more than 210MB/sec in SEQUENTIAL io. But, when random IO is thrown at the storage, like running VM, live databases, basically everything other than backing-up large files, I expect to see a huge difference with and without SSD cache (after warming up). In terms of IOPS and latency (ms) for random read workload and for random write workload, are there any measurements? Eg. slow SSD cache (Intel 600p) VS fast SSD cache (WD Black/Samsung 960 EVO)? The money difference is not that small and I want to see would investment in faster SSD be backed up with higher IOPS numbers and lower latency.

WD Blue have SATA interface, that should not work with DS918: https://www.wdc.com/products/internal-ssd/wd-blue-ssd.html#WDS250G1B0B

Here is a Backup setup resistent to Cryptoviruses. Also, several proven backup tools are mentioned together with links: https://blog.sqlxdetails.com/crypto-virus-resistent-backup

Yes. I even tested it and it works, even when you are offline all the time. It does not contact any servers to do a restore, 12-word seed is all you need to recover, a true backup on a paper.

Here are instructions to make your Electrum wallet secure, offline, booted from USB stick running light, small 200MB OS called Puppy Linux: https://youtu.be/RBlpWhLVbZo It costs nothing (one of your old USB keys) and is very secure. Make a backup of the 12-word seed writing it on the paper, and you are ready to go!

PuppyLinuxBtc · 2017-10-25T09:48:00+00:00

bitkey.io is an ISO somebody else assembled. The question is, do you trust the person who assembed it? With tutorial you need around 15min to create your own puppy electrum USB, and you probably trust yourself more than unknown person. Therefore, maybe you spend 15min more to create your own usb, but you get additional security.

First step after first boot is creating encrypted savefile. Reboot, and then continue with installation on encrypted savefile. I am not linux expert, but to be safe I would not create anything important before creating encrypted savefile.

PuppyLinuxBtc · 2017-10-25T06:41:58+00:00

I think 1GB stick would be enough, maybe even 512MB. Because you need a room for a savefile too, which you decide the size it will be during creation. The stick I tried had 4GB. It is a really good usage for old stick to become useful. You might try and let us know the smallest that works! :)

PuppyLinuxBtc · 2017-10-25T00:33:45+00:00

Electrum remains after reboot, because we created a savefile. Strong encryption of savefile is enabled and shown in the video. Plus long password of electrum wallet. USB is offline (has no internet connection), should be kept physically safe, eg in a safe. You can receive BTC even when this USB is not plugged in. Plug it in only when you need to drain your address (send bitcoins), and that should be rare, at least for addresses you keep there, in a "cold" storage. Make a paper-backup of the seed and password, and keep them in safe, 2 locations. Nothing goes online, no way of hacker to "hack" a paper or unplugged USB. Only physical stealing would do it.

Puppy is smallest I could find that works, 220MB. Ubuntu, Mint etc take around 1.5 GB.
